3.5.1Evacuation and Leak Check—R-134a Pumped Circuit

1.Open all service valves, including those outside the Liebert XDP.

2.Attach a jumper hose from one of the Schrader valve fittings on a pump outlet before the check valve to a Schrader valve fittings after the check valve.

3.Place 150psig (1034kPa; 10.34 bars) of dry nitrogen with a tracer of R-134a in the system.

NOTICE

Risk of overpressurization. Can cause equipment damage.

Do not exceed 150 psig (1034 kPa; 10.34 bars) in the R-134a circuit.

4.Check the system for leaks with a suitable leak finder on the pumps’ suctions lines.

5.After completion of the leak testing, release the test pressure (per local code) and connect to vacuum pump(s) at the Schrader valves.

6.After pulling a deep vacuum for four hours, check the vacuum level and, if it has not changed, break the vacuum with dry nitrogen.

7.Pull a second vacuum to 250 microns or less. Recheck the vacuum level after 2 hours.

3.5.2Insulation

NOTE

Do not insulate piping before checking it for leaks. Insulating pipes before checking them for leaks would prevent easy detection of leaks.

Insulate all piping between the Liebert XDP and its connected cooling modules to prevent condensation where the piping passes through non-conditioned areas.
